Mites, along with ticks, are small arthropods belonging to the subclass Acari and the class Arachnida. The scientific discipline devoted to the study of ticks and mites is called acarology.
The annelids (Annelida, from Latin anellus, “little ring”), also known as the ringed worms or segmented worms, are a large invertebrate phylum, with over 17,000 modern species including ragworms, earthworms, and leeches.
Oligochaetes are full hermaphrodites and produce a ring-like cocoon around their bodies, in which the eggs and hatchlings are nourished until they are ready to emerge.

The red algae, or Rhodophyta, are one of the oldest groups of eukaryotic algae, and also one of the largest, with about 5,000–6,000 species of mostly multicellular, marine algae, including many notable seaweeds.

The green algae are a large, informal grouping of algae consisting of the Chlorophyte and Charophyte algae, which are now placed in separate Divisions. The land plants or Embryophytes are thought to have emerged from the Charophytes.
Ixodes scapularis is commonly known as the deer tick or blacklegged tick, and in some parts of the USA as the bear tick. It is a hard-bodied tick of the eastern and northern Midwestern United States.
The beetle species Popillia japonica is commonly known as the Japanese beetle. It is about 15 millimetres (0.6 in) long and 10 millimetres (0.4 in) wide, with iridescent copper-colored elytra and green thorax and head. It is not very destructive in Japan, where it is controlled by natural predators, but in North America it is a serious pest of about 200 species of plants, including rose bushes, grapes,hops, canna, crape myrtles, birch trees, linden trees and others.
Stinkbugs – Pentatomidae, Greek pente meaning five and tomos meaning section, are a family of insects belonging to order Hemiptera including some of the stink bugs and shield bugs. The scutellum body is typically half of an inch long, green or brown color, usually trapezoidal in shape, giving this family the name “shield bug”. The tarsi are 3-segmented. The forewings of stink bugs are called hemelytra, with the basal half thickened while the apex is membranous (as are the hindwings). The stink bug derives its name from its tendency to eject a foul smelling glandular substance secreted from pores in the thorax when disturbed.
Cicadas are in the superfamily Cicadoidea. Their eyes are prominent, though not especially large, and set wide apart on the anterior lateral corners of the frons. Cicadas live in temperate-to-tropical climates where they are among the most-widely recognized of all insects, mainly due to their large size and unique sound.
Cicadas live underground as nymphs for most of their lives, at depths ranging from about 30 centimetres (0.98 ft) down to 2.5 metres (8.2 ft). The nymphs feed on xylem sap from roots and have strong front legs for digging.
In the final nymphal instar, they construct an exit tunnel to the surface and emerge. They then moult (shed their skins) on a nearby plant for the last time and emerge as adults. The exuvia, or abandoned exoskeleton, remains, still clinging to the bark of trees.
Treehoppers are members of the family Membracidae, a group of insects related to the cicadas and the leafhoppers. About 3,200 species of treehoppers in over 400 genera are known.
The eggs may be parasitised by wasps, such as the tiny fairyflies (Mymaridae) and Trichogrammatidae. The females of some membracid species sit over their eggs to protect them from predators and parasites, and may buzz their wings at intruders. The females of some gregarious species work together to protect each other’s eggs. In at least one species, Publilia modesta, mothers serve to attract ants when nymphs are too small to produce much honeydew. Some other species make feeding slits for the nymphs.

The Candy-Striped Treehopper (Graphocephala coccinea) is a meadow and woodland-dwelling species of brightly colored leafhopper native to North and Central America, from Canada south to Panama.
G. coccinea adults measure 6.7–8.4 mm in length and have vivid blue (or green) and red (or orange-red) stripes on their wings and the top of their thorax combined with bright yellow coloration on their head, legs, abdomen, and elsewhere.
Leafhoppers feed on plant sap with the aid of specialized mouthparts.
Bedbugs are parasitic insects of the cimicid family that feed exclusively on blood. Cimex lectularius, the common bed bug, is the best known, as it prefers to feed on human blood. Other Cimex species specialize in other animals, e.g., bat bugs, such as Cimex pipistrelli (Europe), Cimex pilosellus (western US), and Cimex adjunctus (entire eastern US).
Compound eyes are found among the arthropods and are composed of many simple facets which, depending on the details of anatomy, may give either a single pixelated image or multiple images, per eye. Each sensor has its own lens and photosensitive cell(s). Some eyes have up to 28,000 such sensors, which are arranged hexagonally, and which can give a full 360° field of vision. Compound eyes are very sensitive to motion. Some arthropods, including many Strepsiptera, have compound eyes of only a few facets, each with a retina capable of creating an image, creating vision. With each eye viewing a different thing, a fused image from all the eyes is produced in the brain, providing very different, high-resolution images.
